Description

Technical Field

[0001] The utility model relates to the technical field of high-speed rail brake discs, in particular to an axle-mounted high-speed rail brake disc. Background Art

[0002] When the existing high-speed rail slows down, it slows down by friction between the brake disc and the wheel. However, when it is in use, the friction between the brake disc and the wheel will quickly heat up. The lack of active cooling equipment will reduce the life of the brake disc. For example, a Chinese patent discloses a "high-speed rail locomotive wheel brake disc structure", and its application number is "202020212807.2". This device, through the cooperation between the set spring groove, tension spring, support plate and locating pin and the swing column, by rotating the blocking disc, under the elastic support of the tension spring itself, the spring is stretched, so that the locating pin passes through the pin hole and is placed on the outside of the mounting ring, so that the locating pin is assembled with the corresponding transmission device, thereby facilitating quick positioning, and then facilitating quick installation of the brake disc structure, reducing the difficulty of operation.
